This is a traditional Petrarchan Sonnet Rhyme Scheme, and even though not all lines are perfect rhymes, they are close enough.
For example the rhymes for lines 1, 4, 5, and 8 are borne, worn, turn, forlorn. "turn" is not a perfect rhyme with the 'orn' sound, but it fits in well enough to fill out the rhyme scheme. </span>
